    Irish Chronicles Document Links Between Volcanoes and Weather

    A study of over 40,000 written entries in Irish Annals and ice core measurements shows a strong correlation between the occurrence of volcanic eruptions and extreme cold weather in Ireland over a 1200 year period. Data analyzed in this study cover the period from 431 to 1649, during which time up to 48 volcanic eruptions are identified in Greenland ice core records through deposition of volcanic sulfate in annual layers of ice. You can find the study (open access), published on 6 June 2013 in IOP Publishing's journal Environmental Research Letters, at http://iopscience.iop.org/1748-9326/8/2/024035/article.

    EF-5 Tornado in El Reno, Oklahoma Widest Ever Recorded in US

    The EF-5 tornado that hit El Reno, Oklahoma on May 31st was the widest ever recorded in the US, according to the National Weather Service in Norman Oklahoma. The tornado, which remained on the ground for 40 minutes and reached 2.6 miles across (4.2 km), took the lives of 18 people including storm chasers Tim Samaras, Paul Samaras and Carl Young.

    Atmospheric CO2 Level Tops 400 ppm

    During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well. The level of atmospheric greenhouse gases continues to increase, now over 120 ppm since the Industrial Revolution began. For more on the Keeling Curve, see http://keelingcurve.ucsd.edu/.

Changing Planet: Grapevines and Drought

In this episode, you will learn how climate change is impacting one of our countries most important agricultural crops - grapes.  But grapes are not the only crop in peril.  In previous Changing Planet episodes, you saw how climate change is affecting crops and leaving them more susceptible to drought conditions, infestations and disease.  In the case of grapes, hotter and dryer climates are affecting the flavor of the grapes and the dormancy period of the vines.  It is hoped that by understanding the genetics of the different varieties of grapes, scientists can determine what is changing genetically in response to changing environments.

Those harvesting maple syrup are also concerned about changing lengths of seasons and the impacts shorter seasons will have on overall production.  In this classroom lesson, you will explore changes in the production of maple syrup and decide if you'll need to find something else to put on your pancakes and waffles!
